EMILE BONNIN, OF KREMLIN-BICETRE, FRANCE.

BUGKING APPARATUS.

of KremlinBictre, Seine, France, have invented certain new and usefulImprove ments in Bucking Apparatus, of which the following is aspecification.

This invention relates to a bucking apparatus which is constructed insuch a manner, that the temperature of the lye, which with the devicesof known constructions is limited to about 80, may be raised to theboiling point.

The apparatus essentially consists of an injector of particularconstruction which operates with the aid of hot or cold air.

In the accompanying drawings the apparatus is shown in vertical section.

Figure 1 represents the injector and accessory parts. Fig. 2 shows on asmaller scale a vertical section of the complete tub and its immediateconnections.

The improved apparatus is constructed as follows :Under the bottom ofthe buckingtub a cup or, is fixed which communicates with the tub by theperforations of the plate A cylindrical tube 9 is mounted at the centerof the bottom of cup 64 which is surrounded by a tube of larger diameterh, which is higher than the cylindrical tube 9 and traversing the bottomof the bucking tub reaches up to about 3 inches below the perforatedplate j upon which the textile goods are placed. The rising tube z ofrather large diameter is fixed in the bottom of the tub, concentric withthe protecting tube It. The rising tube 2' is open at the top and at thebottom.

A cylindrical chamber 6 is arranged below the bottom of cup a inprolongation of tube g. In the bottom end of said chamber 6 a conicalnozzle 7) is mounted. The conical annular space around said nozzlecommunicates by a horizontal channel f with a reservoir which containshot or cold, but in any case absolutely dry air.

The apparatus operates as follows :The

lye contained in the bucking tub and in cup a usually fills the tub upto some inches above the perforated partition 7' upon which rests thelinen or other material to be treated. The lye rises through tube 2' andflows over the material to be treated. Steam under pressure is blownthrough the boring c of the conical nozzle b and cold or heated air isblown in through the horizontal channel f, said air forming a mantlearound the steam jet and both jets rising together up through thecylindrical tube 9 and through the protecting tube It into the risingtube 6, accelerate and activate the rising of the lye in sucha manner,that the lye circulates even when it has been heated up to the maximumtemperature, which is very close to the boiling temperature.

It is to be understood that constructional details of the apparatus maybe altered according to requirement, provided that the essentialfeatures of the apparatus, as setforth in the claim be preserved.

What I claim as my invention is An improved bucking apparatus comprisingin combination with the bucking tub and the rising tube for the lye andthe perforated horizontal partition for the material to be treated, acup below the bottom of the bucking tub, a cylindrical tube mounted onthe center of said cup, a protecting tube of larger diameter and greaterheight than said cylindrical tube projecting through the bottom of thebucking tub and reaching up to some inches below the level of saidperforated horizontal partition, a cylindrical chamber extending belowthe bottom of said lye cup in prolongation of the cylindrical tube, aconical nozzle connected with a steam supply in said chamber and ahorizontal pipe connecting said chamber with an air reservoir,substantially as described and shown and for the purpose set forth.
